Chalco, Asia's largest supplier of commercial aircraft engine ring forgings, is a trusted partner for global high-end equipment clients thanks to its robust quality system, certified processes (AS9100D, ISO 9001, NADCAP), and large-scale delivery capability.
Chalco's products serve both military and commercial aircraft engines and are widely used in gas turbines, aerospace, and nuclear power, making it a reliable international supplier of ring forgings and structural components.
Aircraft Engine Components
Core aircraft engine components must operate reliably under high loads and harsh conditions, with stringent strength and performance requirements. Chalco's aluminum forging components have been used in engines such as the GE9X, LEAP, Trent1000, and China's C919 CJ1000, demonstrating outstanding performance and reliability.

Fan Case
The fan case, located at the front of an aircraft engine, is a key structure that encases the fan blades. It serves both as an external protective barrier and as a focus for overall weight reduction.
Chalco Titanium offers fan cases in titanium and aluminum alloys to suit different thrust levels and design approaches.
High-thrust engines or those requiring blade containment typically use Ti-6Al-4V titanium alloy forged fan cases, optionally with composite fiber cladding, for superior impact and heat resistance.
Medium- to low-thrust engines, or those not requiring containment, can use aluminum alloy fan cases such as 2219-T6/T87 or 2618-T851. These provide good thermal strength and dimensional stability at 200–300 °C, with options for welded segmented construction or integral ring rolling.
Aerospace Components
Spacecraft impose extreme demands on structural materials, requiring not only lightweight design but also long-term mechanical stability and sealing performance under low temperatures, vacuum, and high-radiation environments.
Chalco Titanium's high-performance aluminum alloy ring forgings, manufactured with precision, have been successfully used in multiple launch vehicles and spacecraft fuselage sections, demonstrating excellent fatigue resistance and thermal cycle adaptability.

Y-shaped Ring
The Y-shaped ring is a critical connector in rocket structures, designed to withstand and transmit thrust and vibration loads between upper and lower stages. Forged from 2219-T87 or 7050-T7451 aluminum alloys, it combines lightweight design with high strength and excellent fatigue performance. Its good weldability allows integration with cylinders or fuselage sections, ensuring overall structural integrity.
Hanger Frame
The hanger frame is mainly used for connecting and lifting rocket stages or spacecraft modules, requiring both structural strength and dimensional stability. 6061-T6 aluminum alloy significantly improves machining efficiency and, after anodizing, offers excellent corrosion resistance. For models with higher load requirements, 2219 aluminum alloy can be used to balance weldability and strength.
Service Module Metal Shell
The service module shell is a key pressure-bearing component of rocket propellant tanks or auxiliary modules, needing long-term structural stability during launch and orbital maneuvers. 2219-T87 aluminum alloy is widely used for liquid fuel tanks and module shells due to its high strength at low temperatures and excellent weldability.
Rear Skirt Shell
The rear skirt shell, located at the rocket's tail, bears engine thrust and connects to lower structures. It must withstand significant thrust and vibration loads. 2219-T87 and 2618-T851 aluminum alloys are commonly used; the former is suitable for welded assembly, while the latter offers high thermal fatigue resistance, ideal for integral ring forging to ensure mechanical stability of large shells.
Gas Turbine Components
Gas turbines are widely used in power generation, petrochemical, and energy equipment industries, serving as key devices for modern energy conversion and efficient electricity production. Their core components must remain reliable under high-temperature, high-pressure, and long-duration continuous operation. Leveraging advanced aluminum alloy forging technology, Chalco provides a range of critical rings and structural components for gas turbines.
Compressor Casing
The compressor casing is one of the most important ring-shaped components at the front of a gas turbine, forming the airflow channel and providing structural support for the blades. During long-term operation, it must withstand the pressure and vibrations from high-speed airflow.
Chalco Titanium manufactures compressor casings using Ti-6Al-4V and 2219 aluminum alloys. Through near-net ring rolling and NADCAP heat treatment, wall thickness uniformity and geometric precision are ensured. This component significantly improves airflow compression efficiency and turbine lifespan while reducing maintenance costs.
Inlet Guide Ring
The inlet guide ring (Inlet Case & IGV Support Ring) can be made from 6061-T6 aluminum alloy. Its low operating temperature (<150 °C), excellent machinability, and enhanced corrosion resistance through anodizing make it ideal for accessory installation and guide vane support.
Nuclear Power Components
Tube Sheet
The tube sheet is the core component of a heat exchanger, used to secure thousands of heat transfer tubes and separate the primary loop from the cooling water. For highly corrosive primary loops, titanium alloys are typically used. For less corrosive secondary loop heat exchangers or experimental reactor systems, 2219 or 6061 aluminum alloy tube sheets are a mature choice.
- 2219: Offers excellent high-temperature strength and good weldability, stable at 200–300 °C.
- 6061: Easy to machine, and anodizing improves resistance to pitting and crevice corrosion.
Using aluminum alloy tube sheets significantly reduces weight and manufacturing costs while meeting secondary loop heat exchanger requirements.
Damper Support Pad
Damper support pads in reactor cooling systems provide support, vibration damping, and energy absorption. Under moderate load and corrosion conditions, 6061-T6 aluminum alloy pads offer an economical solution. Anodized or hard-coated aluminum enhances wear and corrosion resistance, making it suitable for secondary loop cooling water environments, reducing weight and production cost.
Instrument Tube
Instrument tubes are critical for nuclear power monitoring and control systems, connecting sensors and control devices, requiring high precision and long-term stability. Non-pressure measurement and control lines can use 6061 or 6063 aluminum alloy tubes. These alloys are lightweight, cold-bendable, weldable, and, when anodized, corrosion-resistant, making them ideal for secondary loop and auxiliary system instrumentation.
